How Modeling Works

What's a Value Model?

A value model defines the relative values (aka "multipliers") of the same comic among various grades. You can then plot a single grade's value into your model and extrapolate the values of all other grades.

How to Use This Section

Every grade earns a multiplier value between 0 and 1,000. You can interact with the points on the graph to drag them into position or use the input fields to change them manually.

Experiment with the other controls to find the mix that works for your needs. The valuation table will automatically update using recent sales data.

After you save a single model, make as many copies as you'd like. Further functionality is revealed when multiple models are present for the same comic.

Modeling Example

Let's assume "My Cool Comic #1" regularly sells for $100 in grade 9.2, $50 in 9.0 and $25 in 8.5. This tells us a 9.2 is worth twice as much as a 9.0 and four times as much as an 8.5.

Now let's assume 3 months pass with no 8.5 or 9.2 sales recorded. However, we see multiple sales of 9.0 recorded at an average sale price of $60. We can reasonably assume a 9.2 is now worth $120 (twice the value) and an 8.5 is now worth $30 (half the value).

The multipliers are simply relative values. So the scenario above would turn out the same in any of the below multiplier configurations:

Relative Buffering Days

Modeling buffers are used to identify the time range needed to compare relative values by grade over the life of known sales.

Missing Data Fill Method

This is how you want to fill in the holes when sales data is not known within specific time ranges.
